Disposable arteriovenous hemostatic clamp based on positive and negative tooth buckles

Technical Field

The invention relates to the field of medical instruments, in particular to a disposable arteriovenous hemostatic clamp based on positive and negative tooth buckles.

Background

After the artery or vein puncture, the needle hole left on the artery or vein needs to be stopped bleeding, the conventional hemostasis method generally adopts finger compression, bandage type or air pressure type to stop bleeding, the hemostasis modes generally need the operation of both hands of medical personnel to be completed, the operation is too complex, and the rapid hemostasis is not facilitated; and the tightness of the hemostasis part is not easy to control, the problem that the hemostasis is impossible or the patient is injured due to over-tightness often occurs, and the hemostasis effect is poor.

Therefore, a disposable arteriovenous hemostatic clamp based on positive and negative tooth buckles is urgently needed, and the problems that the conventional arteriovenous puncture hemostasis mode is complex in operation and poor in hemostasis effect can be solved.

Disclosure of Invention

The invention aims to provide a disposable arteriovenous hemostatic clamp based on positive and negative tooth buckles, and the disposable arteriovenous hemostatic clamp is used for solving the problems that the conventional arteriovenous puncture hemostasis mode is complex in operation and poor in hemostasis effect.

In order to achieve the purpose, the invention provides the following scheme:

the invention provides a disposable arteriovenous hemostatic clamp based on positive and negative teeth buckles, which comprises an upper clamp plate and a lower clamp plate, wherein the tail end of the upper clamp plate is connected with a lower hand-pinching hole, the tail end of the lower clamp plate is connected with an upper hand-pinching hole, the front end of the lower hand-pinching hole is hinged with the front end of the upper hand-pinching hole through a pin shaft, a positive teeth buckle is fixed at the upper part of the lower hand-pinching hole, a negative teeth buckle is fixed at the lower part of the upper hand-pinching hole, and the positive teeth buckle is matched with the negative teeth buckle.

Preferably, the upper clamping plate adopts a downward bent arc-shaped structure, and the lower clamping plate adopts an upward bent arc-shaped structure.

Preferably, a silica gel pad is fixed on the inner side of the lower splint.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention aims to provide a disposable arteriovenous hemostatic clamp based on positive and negative tooth buckles, and aims to solve the problems of complex operation and poor hemostatic effect of the conventional arteriovenous puncture hemostasis mode.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

Example 1:

the embodiment provides a disposable sound arteries and veins hemostatic clip based on positive and negative tooth is detained, as shown in fig. 1 and 2, including punch holder 1 and lower plate 2, the end-to-end connection of punch holder 1 has lower hand to hold between the fingers hole 3, the end-to-end connection of lower plate 2 has upper hand to hold between the fingers hole 4, the front end that hole 4 was held between the fingers to lower hand and upper hand are articulated through round pin axle 5, the upper portion that hole 3 was held between the fingers to lower hand is fixed with positive tooth and detains 6, the lower part that hole 4 was held between the fingers to upper hand is fixed with the contra-teeth and detains 7, the positive tooth is detained 6 and is detain.
